This document proposes an IoT-based smart parking system that uses various sensors and communication technologies. IR sensors would detect whether a parking space is occupied and send that data via GSM/GPRS modules to a microcontroller. The availability of free spaces and their locations would then be communicated to users through a mobile application. This would help both users in finding parking more efficiently and owners in managing parking resources better. The system aims to address common parking issues in cities by providing real-time data on spaces and guiding users to available spots using an online interface.
